In this case you could just assign a /29 to the interface, and assign an IP
address to VLAN1 of the switch from the /29, and number both the router
interfaces out of the /29.

You'd also want to assign a default route to the switch with 'ip
default-gateway' pointing to one of the 6509s (or both, with an HSRP
address) probably so that you could access it from further afield than the
6509s directly. If these routers/switches are public also be careful with
telnet access-classes on the VTY and such for security.

Cheers,
Chris.
